Smoke is from central valley, central coast fires

Smoke wafting through the San Jacinto and Santa Rosa mountains Wednesday morning is coming from fires in the Sequoia and Los Padres National Forests, not a new, nearby fire, according to the Forest Services's San Bernardino National Forest division.
The Tweet from SB National Forest:
